This contribution proposes a new symbol synchronization scheme for cyclic prefix based modulation systems, which is disclosed in Ref.[16]. The proposed algorithm involves two steps. By using short-time Fourier transform, ISI-free intervals are estimated from time-frequency spectrum of the received signal, and then an optimum symbol start time is obtained. Computer simulation results show that the algorithm is very robust, and outperforms those based upon time-domain correlations.
